Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1a to 1c are perspective views of a display device DD according to an embodiment of the present invention.

As shown in fig. 1a to 1c, the display plane DD-IS parallel to a plane defined by the first direction axis DR1 and the second direction axis DR 2. The normal direction of the display surface DD-IS (i.e., the thickness direction of the display device DD) IS indicated by a third directional axis DR 3. The front surface (or upper surface) and the rear surface (or lower surface) of each component are divided with reference to the third direction axis DR 3. Hereinafter, the first to third directions are referred to by the same reference numerals as directions indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3, respectively.

As shown in fig. 1a to 1c, the display surface DD-IS includes a display area DD-DA displaying the image IM and a non-display area DD-NDA adjacent to the display area DD-DA. The non-display area DD-NDA is an area where no image is displayed. Fig. 1a to 1c illustrate icon images as an example of the image IM. As an example, the display area DD-DA may be a quadrangular shape. The non-display area DD-NDA may surround the display area DD-DA. However, without being limited thereto, the shape of the display region DD-DA and the shape of the non-display region DD-NDA may be modified.

As shown in fig. 1a to 1c, the display device DD may include a plurality of regions defined according to an operation modality. The display device DD may include a folding area FA folded based on a folding axis FX, a first planar area NFA1 and a second planar area NFA2 adjacent to the folding area FA. The folding area FA is an area substantially forming a curvature.

In the present embodiment, the display device DD is exemplarily illustrated with the folding axis FX defined in parallel with the long axis of the display device DD. However, not limited thereto, the folding axis FX may be parallel to the short axis of the display device DD. Furthermore, in an embodiment of the present invention, the display device DD may have a strip shape without being folded.

As shown in fig. 1b, the display device DD may be folded inside (inner-folding or inner-folding) such that the display surface DD-IS of the first planar region NFA1 faces the display surface DD-IS of the second planar region NFA 2. As shown in fig. 1c, the display device DD may be folded outside (outer-folding or outer-folding) such that the display surface DD-IS exposed to the outside. As shown in fig. 1a to 1c, a display module repeatedly operated to be folded and unfolded may be defined as a foldable display module.

In an embodiment of the present invention, the display device DD may include a plurality of folding areas FA. Furthermore, the folding area FA may be defined according to a form in which the user operates the display device DD. For example, the fold region may also be defined in a diagonal direction intersecting the first direction axis DR1 and the second direction axis DR2 on a plane. The area of the folding area FA is not fixed and may be determined according to the curvature radius. In an embodiment of the present invention, the display device DD may be configured to repeat only the operation modes shown in fig. 1a and 1b, or may be configured to repeat only the operation modes shown in fig. 1a and 1 c.

In the present embodiment, the display device DD applied to a portable telephone is illustrated, but is not limited thereto. In an embodiment of the present invention, the display device DD may be applied to a large electronic device such as a television, a monitor, and the like, and a small and medium electronic device such as a tablet computer, a car navigator, a game machine, a smart watch, and the like.

Fig. 2a to 2d are cross-sectional views of a display device DD according to an embodiment of the present invention. Fig. 2a to 2d illustrate cross-sections defined by the second direction axis DR2 and the third direction axis DR 3. The display device DD of fig. 2a to 2d is simply illustrated in order to explain the stacking relationship of the functional panels and/or functional units constituting the display device.

The display device DD according to an embodiment of the present invention may include a display panel, an input sensor, a reflection preventing unit, and a window. In one embodiment, the input sensor may be omitted. The configurations of at least a portion of the display panel, the input sensor, the reflection preventing unit, and the window may be formed by a continuous process, or at least a portion of the configurations may be bonded to each other by an adhesive member. Fig. 2a to 2d exemplarily illustrate a Pressure Sensitive Adhesive film (PSA) as an Adhesive member. The bonding means described below may include a general adhesive or bonding agent, and is not particularly limited.

In fig. 2a to 2d, respective constituents in the input sensor, the reflection preventing unit, and the window, which are formed by a continuous process with other constituents, are represented as "layers". The input sensor, the reflection preventing unit, and the structure of the window combined with other structures by the adhesive member are denoted as a "panel". Although the "panel" includes a base layer (e.g., a synthetic resin film, a composite film, a glass substrate, etc.) providing a base surface, the "layer" may omit the base layer. In other words, a component or unit denoted as "layer" is arranged on a base surface provided by other components or units.

The input sensor and the anti-reflection unit may be referred to as an input sensing panel, an anti-reflection panel, or an input sensing layer, an anti-reflection layer depending on the presence or absence of the base layer. In the present embodiment, the windows are all illustrated as being applied to the "panel" type, but are not limited thereto.

As shown in fig. 2a, the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection panel RPP, a window WP. In the display device DD, the combined structure configured except the window WP may be defined as a display module.

The input sensing layer ISL is directly disposed on the display panel DP. In the present specification, the "B1 configuration is disposed directly on the a1 configuration" means that no bonding member is disposed between the a1 configuration and the B1 configuration. After the a1 formation is formed, the B1 formation is formed by a continuous process on the base surface provided by the a1 formation. Pressure sensitive adhesive films PSA are disposed between the reflection preventing panel RPP and the window WP and between the input sensing layer ISL and the reflection preventing panel RPP, respectively.

The display panel DP generates an image, and the input sensing layer ISL acquires coordinate information of an external input (e.g., a touch event). Although not separately illustrated, a protective member may be further disposed at a lower side of the display panel DP. The protective member supports the display panel DP and protects the display panel DP from external impact.

The display panel DP according to an embodiment of the present invention may be a light emitting type display panel, and is not particularly limited. For example, the display panel DP may be an organic light emitting display panel or a quantum dot light emitting display panel. The light emitting layer of the organic light emitting display panel may include an organic light emitting substance. The light emitting layer of the quantum dot light emitting display panel may include quantum dots and/or quantum rods, etc. Hereinafter, the display panel DP is described as an organic light emitting display panel.

The reflection preventing panel RPP reduces the reflectance of natural light (or sunlight) incident from the upper side of the window WP. The reflection preventing panel RPP according to an embodiment of the present invention includes a base layer and a color filter. The color filters have a predetermined arrangement. The arrangement of the color filters may be determined in consideration of the emission colors of the pixels included in the display panel DP. The reflection prevention panel RPP may further include a black matrix adjacent to the color filter.

The window WP according to an embodiment of the present invention may include a base layer WP-BS and a light blocking pattern WP-BZ. The base layer WP-BS may have a multilayer structure. The base layer WP-BS may include a glass substrate and/or a synthetic resin film, etc.

The light blocking patterns WP-BZ partially overlap the base layer WP-BS. The light blocking patterns WP-BZ may be disposed at the rear of the base layer WP-BS to define a bezel region (i.e., a non-display region DD-NDA, refer to fig. 1) of the display device DD. The light blocking patterns WP-BZ are colored organic films, and may be formed by coating, for example. In FIGS. 2b to 2d, the window WP does not distinguish the base layer WP-BS and the light blocking pattern WP-BZ, thereby simplifying the illustration.

In an embodiment of the present invention, the light blocking patterns WP-BZ can be omitted. In an embodiment of the present invention, the light blocking patterns WP-BZ may be disposed at the reflection preventing panel RPP. In an embodiment of the present invention, the light blocking pattern WP-BZ may be disposed on the lower side of the window WP by being disposed on another optical member or another synthetic resin film.

As shown in fig. 2b and 2c, the display device DD may include a display panel DP, an reflection preventing panel RPP, an input sensing panel ISP, and a window WP. The stacking order of the input sensing panel ISP and the reflection preventing panel RPP may be changed.

As shown in fig. 2d, the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection layer RPL, and a window WP. Most of the bonding parts may be omitted from the display device DD, and the input sensing layer ISL and the reflection preventing layer RPL are formed on the base surface provided by the display panel DP through a continuous process. The stacking order of the input sensing layer ISL and the reflection preventing layer RPL may be changed.

In an embodiment of the present invention, the reflection preventing layer RPL may include a color filter. A detailed description of the reflection preventing layer RPL will be made later.

Fig. 3 is a plan view of the display area DD-DA according to an embodiment of the present invention.

Referring to fig. 3, a plurality of light emitting regions PXA-R, PXA-G1, PXA-G2 and PXA-B are arranged in the display region DD-DA. A surrounding area NPXA is arranged adjacent to the plurality of light emitting areas PXA-R, PXA-G1, PXA-G2, PXA-B. The peripheral area NPXA sets boundaries of the plurality of light emitting areas PXA-R, PXA-G1, PXA-G2, PXA-B, and prevents color mixing between the plurality of light emitting areas. The plurality of light emitting regions PXA-R, PXA-G1, PXA-G2, PXA-B may define a plurality of pixel rows PXL-1, PXL-2 extending along the second direction DR 2. In fig. 3, the second direction DR2 is defined as an extending direction (or, a row direction) of the pixel rows PXL-1 and PXL-2, and the first direction DR1 is defined as a column direction.

In the present embodiment, the plurality of pixel rows PXL-1, PXL-2 may be divided into two groups. The pixel row PXL-1 of the first group includes a light emitting area (hereinafter, first color area) PXA-R generating a first color of the first color light and a light emitting area (hereinafter, second color area) PXA-B generating a second color of the second color light. The first color areas PXA-R alternate with the second color areas PXA-B in the row direction DR 2. The first set of pixel rows PXL-1 may include a first pixel row PXL-11 and a second pixel row PXL-12. The first pixel rows PXL-11 and the second pixel rows PXL-12 may be alternately arranged in the column direction DR 1.

The arrangement order of the first color area PXA-R and the second color area PXA-B is different from each other for the first pixel row PXL-11 and the second pixel row PXL-12. Within the column direction DR1, the first color area PXA-R of the first pixel row PXL-11 and the second color area PXA-B of the second pixel row PXL-12 may be aligned, and the second color area PXA-B of the first pixel row PXL-11 and the first color area PXA-R of the second pixel row PXL-12 may be aligned.

The pixel row PXL-2 of the second group may include light emitting areas (hereinafter, third color areas) PXA-G1, PXA-G2 that generate a third color of the third color light. The third color areas PXA-G1 and PXA-G2 may be divided into two types of light emitting areas whose shapes are different in plane. The first type area PXA-G1 may have the same shape as the second type area PXA-G2 if rotated 90 degrees in plane. The first type area PXA-G1 may have a shape extending along a first cross direction DDR1, and the second type area PXA-G2 may have a shape extending along a second cross direction DDR2 orthogonal to the first cross direction DDR 1.

The first type areas PXA-G1 alternate with the second type areas PXA-G2 in the row direction DR 2. The second group of pixel rows PXL-2 may include a third pixel row PXL-21 and a fourth pixel row PXL-22. The third pixel rows PXL-21 and the fourth pixel rows PXL-22 may be alternately arranged in the column direction DR 1.

The arrangement order of the first type area PXA-G1 and the second type area PXA-G2 is different from each other for the third pixel row PXL-21 and the fourth pixel row PXL-22. Within the column direction DR1, the first type area PXA-G1 of the third pixel row PXL-21 and the second type area PXA-G2 of the fourth pixel row PXL-22 may be aligned, and the second type area PXA-G2 of the third pixel row PXL-21 and the first type area PXA-G1 of the fourth pixel row PXL-22 may be aligned. However, without being limited thereto, the pixel row PXL-2 of the second group may include only one type of light emitting region whose shape is the same on the plane.

The pixel rows PXL-1 of the first group and the pixel rows PXL-2 of the second group may be alternately arranged in the column direction DR 1. One of the third pixel row PXL-21 and the fourth pixel row PXL-22 is arranged between the consecutive first pixel row PXL-11 and the second pixel row PXL-12, and the other of the third pixel row PXL-21 and the fourth pixel row PXL-22 is arranged between the second pixel row PXL-12 and another one of the first pixel rows PXL-11 consecutive to the second pixel row PXL-12.

In the present embodiment, the light-emitting region of the first color PXA-R, the light-emitting region of the second color PXA-B, and the light-emitting region of the third color PXA-G1, PXA-G2, whose areas are different in plane, are exemplarily illustrated, but not limited thereto. Although the case where the area of the light-emitting region PXA-B of the second color is the largest and the area of the light-emitting regions PXA-G1, PXA-G2 of the third color is the smallest is illustrated, this is merely an example.

In this embodiment, the first color light emitting region PXA-R may generate red light, the second color light emitting region PXA-B generates blue light, and the third color light emitting regions PXA-G1, PXA-G2 generate green light. However, it is not limited thereto. The color light emitted from the light emitting regions PXA-R of the first color, PXA-B of the second color, and PXA-G1, PXA-G2 of the third color may be selected from a combination of three color lights capable of generating white light by mixing the emitted color lights.

As shown in fig. 3, the number of the third color areas PXA-G1 and PXA-G2 is greater than (about twice) the number of each of the first color areas PXA-R and the second color areas PXA-B, so reflected light reflected at the display area DD-DA may have predetermined characteristics. In particular, in a state where the display device DD (refer to fig. 1) is turned off, the reflected light of black may have a predetermined color sensation. The reflected light is light in which external light (e.g., natural light) is reflected at the display area DD-DA.

Even if the reflectance is reduced due to the reflection preventing units RPP, RPL described with reference to fig. 2a to 2d, the color sensation of the reflected light may have a predetermined characteristic. According to the present embodiment, even if the light-emitting regions PXA-R, PXA-G1, PXA-G2, PXA-B have the arrangement described with reference to fig. 3, the color sensation of reflected light can approach the color sensation of pure black. The amount of color shift of the reflected light may be minute for the display device according to the present embodiment, compared to the comparative example including the polarizing plate as the reflection preventing unit. Hereinafter, the relationship between the light-emitting regions PXA-R, PXA-G1, PXA-G2, PXA-B and the reflection preventing units RPP, RPL will be described in detail.

Fig. 4 is a cross-sectional view according to I-I' of fig. 3. Fig. 4 particularly illustrates the display panel DP described with reference to fig. 2a to 2 d.

The display panel DP may include a base layer BL, a circuit element layer DP-CL, a display element layer DP-OLED, and an upper insulating layer TFL. The stacked structure of the display panel DP is not particularly limited.

Referring to fig. 4, the display panel DP may include a plurality of insulating layers as well as semiconductor patterns, conductive patterns, signal lines, and the like. The insulating layer, the semiconductor layer, and the conductive layer are formed by coating, deposition, or the like. Thereafter, the insulating layer, the semiconductor layer, and the conductive layer may be selectively patterned by photolithography. In this way, the semiconductor patterns, the conductive patterns, the signal lines, and the like included in the circuit element layers DP-CL and the display element layers DP-OLED are formed.

The base layer BL may include a synthetic resin film. In addition, the base layer BL may include a glass substrate, a metal substrate, an organic/inorganic composite substrate, or the like.

At least one inorganic layer is disposed on an upper surface of the base layer BL. The buffer layer BFL improves the bonding force between the base layer BL and the semiconductor pattern. The buffer layer BFL may include a silicon oxide layer and a silicon nitride layer. The silicon oxide layer and the silicon nitride layer may be alternately stacked.

A semiconductor pattern is disposed on the buffer layer BFL. The semiconductor pattern may include polysilicon. However, it is not limited thereto, and the semiconductor pattern may also include amorphous silicon or metal oxide.

Fig. 4 illustrates only a part of the semiconductor patterns, and the semiconductor patterns may be further arranged on the plurality of light emitting regions PXA-R, PXA-G1, PXA-G2 and PXA-B (refer to fig. 3) on a plane. The semiconductor patterns may be arranged in a specific rule throughout the plurality of light emitting regions PXA-R, PXA-G1, PXA-G2, PXA-B (refer to fig. 3). The semiconductor pattern is electrically different according to doping characteristics such as whether it is doped or not. The semiconductor pattern may include a doped region and an undoped region. The doped region may be doped with an N-type dopant or a P-type dopant. The P-type transistor includes a doped region doped with a P-type dopant.

The doped region has a conductivity greater than that of the undoped region and substantially functions as an electrode or a signal line. The undoped region substantially corresponds to the active region (or channel) of the transistor. In other words, a part of the semiconductor pattern may be an active region of the transistor, another part may be a source or a drain of the transistor, and another part may be a connection electrode or a connection signal line.

As shown in fig. 4, the source S1, the active region a1, and the drain D1 of the transistor T1 are formed from a semiconductor pattern. Fig. 4 illustrates a portion of the connection signal line SCL formed from a semiconductor pattern.

The input sensing layer ISL may include a first insulation layer IS-IL1, a first conductive layer IS-CL1, a second insulation layer IS-IL2, a second conductive layer IS-CL2, and a third insulation layer IS-IL 3. In an embodiment of the present invention, the first insulating layer IS-IL1 and/or the third insulating layer IS-IL3 may be omitted.

Each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 may have a single-layer structure or a multi-layer structure stacked along the third direction axis DR 3. The conductive layer of the multi-layered structure may include at least two of a transparent conductive layer and a metal layer.

Hereinafter, a case where the first conductive layer IS-CL1 includes a first conductive pattern and the second conductive layer IS-CL2 includes a second conductive pattern will be described. Each of the first and second conductive patterns may include a sensing electrode and a signal line connected thereto. The first conductive pattern and the second conductive pattern may be arranged to overlap with a later-described partition pattern BM.

The first, second, and third color filters CF-R, CF-B, and CF-G1 reduce the reflectance of external light. Each of the first to third color filters CF-R to CF-G1 passes light of a specific wavelength range and absorbs light other than the corresponding wavelength, thus absorbing most of natural light and reflecting only a part thereof.

The first, second, and third color filters CF-R, CF-B, and CF-G1 include a matrix resin and a dye and/or pigment dispersed in the matrix resin. The matrix resin can be formed of a variety of resin compositions, which can be generally referred to as binders, as a medium in which a dye and/or a pigment is dispersed.

Fig. 6a to 6e illustrate a part of the region of fig. 3 in an enlarged manner. The manufacturing process is described in detail centering on the six light emitting regions PXA-R1, PXA-R2, PXA-B1, PXA-B2, PXA-G1, PXA-G2 of the first pixel row PXL-11, the second pixel row PXL-12, and the third pixel row PXL-21 arranged therebetween.

As shown in fig. 6b, the division pattern BM is formed. The division pattern BM may be directly formed on the input sensing layer ISL shown in fig. 5. After the resin layer including the base resin and the black component is formed, the first opening portion OP-BR1, the second opening portion OP-BR2, the third opening portion OP-BB1, the fourth opening portion OP-BB2, the fifth opening portion OP-BG1, and the sixth opening portion OP-BG2 are formed in the resin layer by a photolithography process.

As shown in fig. 6c, third color filters CF-G1 and CF-G2 corresponding to the fifth light-emitting region PXA-G1 and the sixth light-emitting region PXA-G2 are formed. The third color filter CF-G1 corresponding to the fifth light-emitting region PXA-G1 and the third color filter CF-G2 corresponding to the sixth light-emitting region PXA-G2 may be spaced apart from each other.

After forming a color filter layer on the input sensing layer ISL as shown in fig. 5, the color filter layer is patterned through a photolithography process. In an embodiment of the present invention, the third color filter CF-G1 corresponding to the fifth light-emitting region PXA-G1 and the third color filter CF-G2 corresponding to the sixth light-emitting region PXA-G2 may also be patterned to have an integral shape.

Hereinafter, the third color filter CF-G1 corresponding to the fifth light emitting region PXA-G1 will be described as a center. The edge of the third color filter CF-G1 may overlap the division pattern BM.

As shown in fig. 6d, second color filters CF-B1 and CF-B2 corresponding to the second light-emitting region PXA-B1 and the third light-emitting region PXA-B2 are formed. After forming a color filter layer on the input sensing layer ISL as shown in fig. 5, the color filter layer is patterned through a photolithography process. Fig. 6d illustrates a pattern (or, a color filter pattern) CF-B1 corresponding to the second light emitting region PXA-B1 and a pattern CF-B2 corresponding to the third light emitting region PXA-B2 of the second color filters CF-B1, CF-B2.

A portion of the second color filters CF-B1, CF-B2 overlapping the division pattern BM is arranged on the third color filter CF-G1. The case where a part of the second color filters CF-B1, CF-B2 overlapping the division pattern BM is entirely arranged on the third color filter CF-G1 is not limited. As long as a part of the second color filters CF-B1, CF-B2 overlapping the division pattern BM is arranged on the third color filter CF-G1.

In one embodiment, the second color filters CF-B1 and CF-B2 may have an integral shape without being divided into a plurality of patterns. Although not separately illustrated, the color filter corresponding to the light emitting region that generates blue light may be formed through a single process.

As shown in fig. 6e, the first color filters CF-R1 and CF-R2 corresponding to the first light emitting region PXA-R1 and the fourth light emitting region PXA-R2 are formed. A portion of the first color filters CF-R1, CF-R2 overlapping the division pattern BM overlaps on the third color filter CF-G1. The case where a part of the first color filters CF-R1, CF-R2 overlapping the division pattern BM is entirely arranged on the third color filter CF-G1 is not limited. As long as a part of the first color filters CF-R1, CF-R2 overlapping the division pattern BM is arranged on the third color filter CF-G1.

In one embodiment, the first color filters CF-R1 and CF-R2 may have an integral shape without being divided into a plurality of patterns. Although not separately illustrated, a color filter corresponding to a light emitting region that generates red light may be formed through a single process. In the above, the first color filters CF-R1 and CF-R2 are formed after the second color filters CF-B1 and CF-B2 are formed, but not limited thereto. The order of formation thereof may be changed.

Referring to FIG. 6e, the first color filters CF-R1, CF-R2 and the second color filters CF-B1, CF-B2 cover a portion of the third color filter CF-G1 in the peripheral region NPXA. Accordingly, the area of the third color filter CF-G1 exposed to the outside is reduced when viewed in a plan view.

As described with reference to fig. 3, since the number of the third color areas PXA-G1, PXA-G2 is greater than the number of the first color areas PXA-R and the number of the second color areas PXA-B, the number of patterns of the third color filters CF-G1, CF-G2 is greater than the number of patterns of the first color filters CF-R1, CF-R2 and the number of patterns of the second color filters CF-B1, CF-B2. When comparing the occupied areas, the areas of the third color filters CF-G1, CF-G2 are larger than the areas of the first color filters CF-R1, CF-R2 and the areas of the second color filters CF-B1, CF-B2.

Therefore, as described above, the area of the third color filter CF-G1 exposed to the outside is reduced, so that the deviation of the areas of the first, CF-R1, CF-R2, second, CF-B1, CF-B2, and third color filters CF-G1, CF-G2 exposed to the outside can be reduced when viewed in a plan view. As a result, the reflected color sensation of black can be prevented from being converted into a specific color.

According to fig. 8, unlike the embodiments of fig. 7a to 7d, in the peripheral region NPXA, a portion of the first bridge portion P3 and the second bridge portion P4 may not overlap with the second color filters CF-B1 and CF-B2. One of the two second color filters CF-B1, CF-B2 may be a one-side color filter (or, a first color filter pattern) CF-B1, and the other is defined as the other-side color filter (or, a second color filter pattern) CF-B2.

In plan, the first bridge portion P3 may be spaced apart from one side color filter CF-B1, and the second bridge portion P4 may be spaced apart from the other side color filter CF-B2. Through the spaced regions, a portion of the third color filter CF-G1 disposed at the lower side of the first and second color filters CF-R and CF-B1 and CF-B2 may be exposed.
